I really would love to be able to use your library for a project, but I can't seem to make it work, not even with the simplest example... Any help on what I'm missing would be great.

Thanks in advance!

Luis.

sorry if its not answering the original question

but since its have save error message

I manage to fix my problem in heroku
by using heroku-18 stack

this buildpacks https://github.com/ReforgeHQ/heroku-buildpack-python
with python 3.8.1

I also manage to fix this problem using heroku-20 stack and python 3.8.10 in here #151

@ljoglar make sure your python have --enable-shared
to check it first run this on your bash/terminal
python3 -msysconfig | grep enable-shared

if there is no result that show --enable-shared on your python

you need to recompile ur python with --enable-shared

@buncis, could you detail how you managed to recompile your py interpreter with --enable-shared? I spent many hours trying to do so in my M1 mac but failed miserably.
